The reciprocating wear behaviour of TiC–304L stainless steel composites prepared by melt infiltration

The effects of Mo2C additions on the microstructure and sliding wear of TiC0.3N0.7–Ni3Al cermets

“…It is broadly observed that as the applied load and/or binder content were increased so too was the resultant wear rate, although there is some apparent scatter in the data. This increasing wear rate trend was also seen in similar cermet systems using the same testing apparatus and counter face material [12,13,32]. It is believed that one of the main controlling factors that contributes to the increased wear rates of the samples with higher binder contents is the fact that there is a decreased amount of the hard, wear resistant ceramic phase, thus resulting in decreased contiguity seen throughout the samples.…”

“…In this instance it therefore appears that incorporation of Mo 2 C into the cermet structure actually raises the COF measurably. The tribolayer composition itself will be dictated in part by the metallic binder, and this effect is further highlighted in related work, based on TiC cermets prepared with a 304 L stainless steel binder [32], where significantly lower mean COF values were determined (between 0.18 and 0.38).

“…It can often be composed of oxides from the components that make up the structure of the tribo-pair, as noted in prior cermet wear studies [12,13,32]. Table 2 shows the chemical composition of the various tribolayers formed in the TiC 0.3 N 0.7 cermets as the amount of Mo 2 C was varied, determined by EDS analysis, for a constant applied load of 60 N. It is apparent that the O content for all the different compositions remained fairly consistent at~50 at.%.…”

Sintering and mechanical properties of TiB2-TiC-Ni using submicron borides and carbides

“…Similarly, titanium carbide (TiC) based cermet, TiC-TiN-(Ni, Mo, Co), is also an ideal candidate for cutting tool materials owing to its excellent wear resistance and high hardness [8][9][10][11][12]. Except cutting tool materials, both TiB 2 and TiC also have various other crucial applications from structural to electronic fields such as impact resistant armor, wear resistance components, corrosion resistance coatings, and electrode materials [1,2,13,14]. Comparing with monolithic TiB 2 or TiC cermets, several reports indicate that TiB 2 -Ti(C,N)-(Ni,Mo) composite has outstanding properties including hardness, fracture toughness, and strength [5][6][7]15].…”

Efecto del porcentaje de refuerzo frente al desgaste en compuestos de matriz metálica sinterizados con descarga luminiscente anormal

“…La demanda de componentes de acero fabricado por pulvimetalurgia (PM) está aumentando de manera significativa y diferentes aceros PM han encontrado aplicaciones, principalmente en el sector de la automoción para sistemas de motor y de transmisión (Ceschini et al, 2006), tal es el caso del acero austenítico 316, que a pesar de presentar baja resistencia al desgaste es uno de los más empleados en dicho sector (Renedo, 2010;Sheikhzadeh y Sanjabi, 2012;Onuoha et al, 2013). Mediante PM se han obtenido materiales compuestos que presentan una buena distribución de las partículas para los diferentes contenidos de refuerzo que proporciona a los materiales unas propiedades mecánicas y estructurales aceptables (Amigó et al, 2007).…”
